Assign resistance boundary condition.
- Parameters:
- objects
list
orstr
A list of objects to which the resistance condition will be assigned. It can be a single object (a string) or multiple objects specified as a list.
- boundary_name
str
,optional
The name of the boundary object that will be created. If not provided, a unique name is generated. The default is
None
.- total_power
str
,float
,or
dict
orBoundaryDictionary
,optional
The total power transferred to the fluid through the resistance volume. It is specified as a string with a value and unit, a float where the default unit “W” is used. Assign a transient condition using the result of a function with the

for all three directions.- quadratic_loss_free_area_ratio
list
of
floats
orlist
of
strings
,optional
Three values representing the quadratic loss coefficient for each direction (X, Y, Z) in the loss model. Relevant only if
loss_type=="Device"
. Default is1
for all three directions.- power_law_constant
str
orfloat
,optional
Specifies the coefficient in the power law equation for pressure loss. Default is
1
